Abstract
Under different assumptions about the total number of genes, the number of housekeeping and tissue-specific genes, and the difference in the number of mRNAs per cell for functional and nonfunctional genes, significantly different results can be expected from screening random cDNA clones. We have developed gene expression models as a guide for interpretation of experimental results. For statistical, biological, and technical reasons, the search for 100,000 plus genes and discrimination between nonfunctional, housekeeping, and tissue-specific genes requires the analysis of up to 10 million clones from 20 to 50 tissues. Oligonucleotide hybridization of dense clone blots is an inexpensive and fast way to screen such large clone sets. Our preliminary results on control clones and thousands of cDNA clones from an infant brain library demonstrate the feasibility of the method.
